new video editing techniques

I've been working with MSI afterburner for recording video and audacity to capture my voice at the same time.  My main issue right now is my microphone isn't picking up everything so I'll need to increase the sensitivity. That and I may also need to lower the in game volume of games I'm playing. Here's my most recent venture using World of Tanks.  I kept a decent frame rate throughout the match which I wasn't expecting as I remembered MSI  afterburner slowing the game's performance down but it hung around a steady 30 FPS which is adequate.
